This drawing shows the carbon cycle on Earth. A majority of the carbon is held in the carbonate rocks underneath the soil. Carbon is exchanged between the atmosphere and ocean, while plants and trees take in carbon dioxide and release oxygen. Also notice that carbon is released through the soils and by factories.

Carbon is everywhere on Earth! You can find it in trees, rocks, the oceans, even in the air! Carbon dioxide is a common gas you can find in our atmosphere. It is the source of the carbon cycle.
Carbon dioxide goes from one place to another. For example, the gas can go from the air into the oceans, and then into the trees. Carbon dioxide does this over and over, and this is called the carbon cycle.
